We always use a chain that's much larger/heavier than necessary. One that you know isn't going to break for the task at hand. I personally wouldn't use a cable unless it was a VERY heavy one. Something meant for a dozer. lol I'm extremely weary of cables. A cable choker would be very handy on stumps though.
We never worried about the length as far as safety due to having overly heavy chains, but I think our heavy tractor chain is around 30ft +/- long and is 3/4" grade #100 chain rated around 36,000lbs and being grade 100 is guaranteed for 2.5 times the working load limit. It's an old quarry chain spec'd for lifting. We usually use a 3/8" though, due to it being easier to lift, carry, and for ease of sliding under logs, etc.
With larger chains, you're almost guaranteed to break a drawbar or hitch before you snap a chain, but it never hurts to visually inspect all of the links. We've destroyed several rims over the years pulling things that were too large. Just be aware that any chain, cable, or strap could break or come loose at any time and do major damage or kill someone. Have everyone stand well clear of the operating area, and have the money to replace windows, damaged equipment, etc.
I've contemplated getting my federal explosives license just for removing stumps. Much less labor and the license doesn't cost much, but the record keeping and storage requirements are just too involved to deal with these days.
Here what I built yesterday for the job, took 40 minutes with the chain saw, might work, might not, I'll find out today.
Wish I could film it but I am alone.
I'll update with pictures
